Abstract:Conduct anaerobic biochemical experiments on acrylic acid wastewater diluted with different COD levels, and characterize the unit mass COD and methane of the experimental wastewater
When the yield of acrylic acid wastewater is diluted to COD ≤ 2880mg/L, the wastewater exhibits non-toxic inhibition on anaerobic sludge; When the acrylic acid wastewater is diluted to a COD of 2880-5760mg/L, the wastewater has a toxic inhibitory effect on anaerobic sludge, and the higher the COD of the wastewater, the greater the toxicity inhibition; When the acrylic acid wastewater is diluted to COD>5760mg/L, the wastewater is completely toxic to anaerobic sludge.
